A stock trades at Rs 400 in the spot market. The risk-free rate is 9% per annum with continuous compounding, ignoring dividends. Using F = S × e^(rT), what is the approximate fair price of a futures contract expiring in 3 months? (Take e^0.0225 = 1.0228)

The fair futures price is about Rs 409.12. With continuous compounding, F equals spot times e raised to rT, where rT is 9% times 0.25, or 0.0225. Multiplying Rs 400 by 1.0228 gives Rs 409.12, reflecting the cost of carry for three months.

  1. ARs 409.12Correct
  2. BRs 436.00
  3. CRs 400.00
  4. DRs 390.88

Explanation

T = 3/12 = 0.25, so rT = 0.09 × 0.25 = 0.0225. F = 400 × 1.0228 = 409.12. Using 9% for a full year (436) ignores the time fraction; Rs 390.88 wrongly subtracts the carry cost.
